¢ Initialisation string
Users of communication programs will frequently encounter
references to the initialisation string. This is a string of
commands which are sent to the modem prior to the call being
made.
The standard solution for users of the PROCOMM program is
the following initialisation string:
ATE0S7=60S11=70S0=0V1X1 prt
For users of the modem this signifies:
EO
No echo to be made of the entered commands on the screen
$7=60
This instructs the modem to wait 60 seconds on the carrying
wave. (The manufacturers setting is 50 seconds).
$11=70
The modem will use less time to call the number when tone
signals are employed. The modem may however have a lower
value than 70. Therefore always use S11=70. Note that certain
switchboards are not able to accept signals sent at this rate. It is
safer to use the manufacturers setting.
S0=0
The modem shall not reply when someone calls in. (This
command is superfluous in that the modem has this as the
default setting).
Vi
This selects the full message code (as for example CONNECT
9600). This is also superfluous for the modem which has this as
the manufacturers setting.
x1
The modem sends the messages CONNECT or CONNECT
9600. It will not detect the dialling tone or the busy signal. (The
manufacturers setting is X4).
Read more about X4 under the section on AT «General
commands».

Maintenance and repairs
The modem is maintenance free. However, you should keep the
apparatus dust free.
Parts should only be changed by authorised dealers.
